For starters it includes all of the data in LibraryThing’s Common Knowledge project, our groundbreaking “fielded wiki” for interesting book information (see original blog post). It includes fields like series, important characters, important places, author dates, author burial places, agents, edits, etc. If you’re interested in building or enhancing book-data applications, this should be very interesting.

Common Knowledge is always in progress, but the results so far have been quite impressive. Members have made over 500,000 edits, and certain data types have become exceedingly useful and comprehensive. I’m particularly proud of our Series coverage (eg., Star Wars), better—we think—than any commercial series data.

Oh, and it’s free! The data is made available under the highly permissive Creative Commons Attribution Share Alike license.

This makes me want to get back into developing so I can create neat new sites with this information!! Read the rest from Tim.
